in thread How to store matched $1 values one by one to array?

if($line =~ /^.*:agent_id=>(.+?),/){ # Calls count based on call type my $agent_value=$1; my $agent_value=~s/\"//g; push @agent_ids, $agent_value; print Dumper\@agent_ids; }

Before while loop I have declared the @agent_ids and then added the push function with array and scalar variable.

While printing the @agent_ids variable it printed the undef in array.

I don't know why it is printing the undef values instead of exact values.

    Just remove the second lexical declaration and the code works.

    'warnings' says: "my" variable $agent_value masks earlier declaration in same scope at ...

    Remove the second my before $agent_value. It resets its value. Also, turn on warnings to be warned against the practice of redeclaring a variable.
